Question

find the perimeter of rectangle whose area is 30 sq m and length of rectangle is = 5m​

Answer 1

Answer:

Area of rectangle - lb

30 = 5 × b

30/5= b

b= 6

so ,

perimeter of rectangle = 2(a+b)

= 2(5+6)

= 10 + 12

= 22

Answer 2

Given

Area = 30 m²

Length = 5 m

Area = L × B

30 = 5 × B

Breadth = 6 m

Perimeter = 2(L + B)

Perimeter = 2(5+6)

Perimeter = 2 × 11 m

Perimeter = 22 m
