Question

the area of a rectangle field is 90 square meter if its length is 18m, the. its perimeter is (a)46m (b)50m (c)55m (d)26m​

Answer 1

Step-by-step explanation:

Area of rectangle = 90

l*b= 90

18* b= 90

b=90/18

b=5

perimeter of rectangle = 2(l+b)

=2(18+5)

=2*23

=46m

Answer 2

Answer:

Option A) 46 m is correct

Step-by-step explanation:

Area = lb ( length*breadth)

L = 18 m B = ?

18*b = 90

b = 90/18 = 5 m

Perimeter = 2 (l+b) = 2 (18+5) = 2 (23) = 46 m
