Question

The area of a field of length 40 m and width 15 m was wrongly calculated as 800 sq. m. Find the error percent.​

Answer 1

hey,

here ur answer

area = 800 sq.m

l * b = 800

80 * b = 800

b = 800/80

b= 10m

Perimeter = 2(l+b)

                = 2 (80+10)

                = 2*90

                =  180 m

hence, perimeter is 180 metres.
