Question

1. Find the perimeter and area.






















A. Rectangle, L = 12 m and B = 9.5 m

B. Square, side = 8 m

C. Rectangle, L = 24.2 cm and B =16.8cm

D. Square, side = 14.5 cm​

Answer 1

A. Perimeter of rectangle = 2(l+b)
=2(12+9.5)
=2(21.5)
=43m
Area of rectangle = l*b
=12*9.5
=114 sq. M

B. Perimeter of square = 4*side
=4*8
=32m
Area of square = side*side
=8*8
=64 sq. M

C. Perimeter of rectangle = 2(l+b)
=2(24.2+16.8)
=2(41)
=82cm
Area of rectangle = l*b
=24.2*16.8
=406.56sq. Cm

D. Perimeter of square = 4*side
=4*14.5
=58cm
Area of square = side*side
=14.5*14.5
=210.25sq. Cm
