Answer:
breadth = 25m
length= 35m
Step-by-step explanation:
perimeter is distance all round a figure
in a rectangle we have two pairs of opposite but equal lines
breadth = 2x( because of the two breadths in a rectangle) - 20
length = 2x( because of the two lengths in a rectangle)
perimeter = 2x + 2x - 20
120 = 4x - 20
120 + 20 = 4x
140 = 4x
35 = x
to get the dimensions, we have to divide by 2 as we took both parts of each dimension
breadth =<u> 2x - 20</u>
2
<u>=2(35) - 20</u>
2
<u>= 70 - 20</u>
2
<u>= 50m</u>
2
= <u>25m</u>
length =<u> 2x</u>
2
<u>= 2(35)</u>
2
<u> = 70m</u>
2
= <u>35m</u>
