Question

Find the area of the shaded portion.​

Answer 1

Answer:

if one corner is 10 the second also will be 10

Step-by-step explanation:

we have to subtract extra portion 90-10=80

it is a rectangle so area of rectangle is length*breadth

so 80*30=2400cm^2

Answer 2

Step-by-step explanation:

The figure is a paralleogram. So, the sides either from the shaded portion are of same length. Hence, the measure of the bottom and top shaded part

= 90-10

= 80

The measurement of left side is give. Hence, measure of right side will be measure of left side.

Therefore, measure of both sides will be 30cm each.

So, area

= 80 × 30

= 2400cm.
