The width of the triangle is 3/4 the length. The perimeter is 252cm. What is the width of the triangle.
1 answer:
Answer:
C). 54 cm.
Step-by-step explanation:
I think you mean a rectangle .
If the length is x then the width = 0.75x (because 3/4 = 0.75).
Perimeter = 2*length + 2*width.
252 = 2x + 2*0.75x
252 = 2x + 1.5x
252 = 3.5x
x = 252 / 3.5
= 72 which is the length,
The width = 3/4 * 72
= 54 cm.
