Question

Explain the answer please

Answer 1

Answer:

Step-by-step explanation:

let the length be7x and breadth be4x

area=17500m²

we know that,

area of rectangle=length*breadth

17500=7x*4x

17500=28x²

x²=17500/28

x²=625

x=25

so, 7x=7*25=175 and 4x=4*25=100

now,

perimeter=2(length+breadth)

                =2(175+100)

                =2*275

                =550m

$\red{\bold{Answer♡♡}}$

Let the length and breadth of rectangular park be 7x and 4x

Area = 17500 sq.m

17500 = 7x*4x

17500 = 28x^

17500/28 = x^

625 = x^

25 = x

putting the value of x

= 7(25) = 175m

= 4(25) = 100m

Perimeter

= 2(l+b)

= 2(175+100)m

= 2(275)m

= 550m
