Question

fIND area and perimeter ​

Answer 1

Answer:

a) Rectangle

Area = L x B

          = 6 x 2 = 12$cm^2$

perimeter = 2(L + B )

                 = 2 ( 6 + 2 )

                 = 2 x 8 = 16cm

b) Square

Area = $Side^2$

        = $7^2 = 49km^2$

Perimeter = 4 x side = 4 x 7 = 28km

c) Triangle

Area = 1/2 x base x height = 1/2 x 8 x 6 = 24$cm^2$

Perimeter = side 1 + side 2 + side 3 = 6 + 8 + 10 = 24

d) Triangle

Perimeter = side 1 + side 2  + side 3 = 5 + 2+ 3.5 = 10.5mm

Area = 1/2 x base x height = 1/2 x 2 x 3.5 = 3.5$mm^2$
