Question

1. Find the area of the shaded portion in each case 8m,4m,8m,4m

Answer 1

Answer:

1-Area of bigger square=(side)sq.

=(8m)sq

=64sq.m

Area of smaller square=(side)sq

=(4m)sq =16sq.m

now,

area of shaded portion = area of bigger square - area of smaller square

64sq.m - 16sq.m

=48sq.m is the area of shaded portion

2-area of bigger rectangle=L×B

=24m×20m=480sq.m

area of smaller rectangle=L×B

=22m×18m=396sq.m

now,

area of shaded portion = area of bigger rectangle - area of smaller rectangle

480-396=84

84sq.m is the area of shaded portion.
