The lengths of three sides of a triangle are all primes, and the perimeter of the triangle is 4343. Find the sum of all possible value(s) of the longest side.
The lengths of three sides of a triangle are all primes, and the perimeter of the triangle is 17. Find the sum of all possible value(s) of the second longest side.
The lengths in cm of three sides of a triangle are three consecutive odd numbers. Knowing that the perimeter of the triangle is 39cm, find the length of the longest side of the triangle. Show your work.
The lengths in cm of three sides of a triangle are three consecutive odd numbers.
Knowing that the perimeter of the triangle is 40.5 dm, find the length of the longest side of the
triangle.
A.137cm
B.135cm
C.143cm
D.145cm
40.5dm = 405cm
The length of each side averages to : 405 / 3 = 135 ( cm )
The length of the longest side of the triangle is : 135 + 2 = 137 ( cm )
The answer is A.137cm.
three lines dissect a big triangle into four triangles and three quadrilaterals. the sum of the perimeters of the three quadrilateral is 25 cm, the sum of the perimeters of the four triangle is 20 cm. the perimeter of the big triangle is 19 cm. how big is the sum of the lengths of the three dissecting lines?
A square and a triangle have equal perimeters. The lengths of three sides of the triangle are 6.2cm, 8.3cm and 9.5cm. The area of the square is...
Perimeters of a triangle is: 6.2+8.3+9.5=24cm
But a square and a triangle have equal perimeters
⇒Perimeters of a square is 24cm
So: the side of a square=\(\dfrac{24}{4}\)=6
Other way: the area of a square=a.a
⇔Ssquare=6*6=36 (cm2)
in a magic triangle, each of the six whole numbers 10; 11; 12; 13; 14; 15 is placed in one of the circles so that the sum, S, of the three numbers on each side of the triangle is the same. The largest possible value for S is
