Question

find the perimeter of a rectangle whose area length are 6300 m2 and 90 m respectively​

Answer 1

Answer:

let the l =90m

b = ?

a = 6300m2

l × b =a

90m × ? = 6300m2

we will transfer 90m at opposite side

6300m2÷90m = 70m

So the breadth is 70.m

Answer 2

Answer:

320

Step-by-step explanation:

L=90m

A=6300m2

B=6300m2/90m

B=70

Perimeter=2(l+b)

=2(90+70)

=2*160

=320
