Question

The length of a rectangle is 7 more than its breadth if it perimeter is 15 M find the length and breadth of the rectangle

Answer 1

Hi !!!

This is your answer....

Given ::::---

Perimeter of rectangle = 2(l+b) = 15 m.
Length is 7 m more than the breadth.

Let the length be l and breadth be b.
So.. l = b+7.

So... putting values of length and breadth in perimeter of rectangle formula......

》2 (l + b) = 15
》》2 ( b + 7 + b) = 15
》》》2b + 14 + 2b = 15
》》4b = 1
》b = 1/4. = 0.25 m

Also.
l = b + 7
length = 1/4 +4
= 1/4 + 16/4
= 17/4 = 4.25 m.

Hence... the length and breadth are 4.25 m and 0.25 respectively........ ...

HOPE IT HELPSSSS.......
