Chapter 2: Q40. (page 93)

Find the value of x for the given triangle or rectangle

Perimeter 352 ft

Short Answer

Expert verified

Length of side of rectangle isx=66 feet.

Step by step solution

01

Step-1- Using perimeter of rectangle formula

We know that,

Perimeter of rectangle =2l+b, where l=length of rectangle and b=breadth of rectangle.

02

Step-2-Calculating side of rectangle 

On substituting values, we get

352=2110+x352=220+2x
03

Step-3-Solving for value of x

Subtracting 220on both sides, we get

352-220=2x+220-2202x=352-2202x=132

Dividing with2on both sides, we get

2x2=1322x=1322x=66

Therefore, length of breadth of rectangle =x=66 feet.
