Answer 1

Answer:

Answer is 2906.25m²....

Step-by-step explanation:

First find the area of rectangle ABCD,

Ar(ABCD) = length x breadth

= 40 x 80

= 3200m²

Now find the are of rectangle IKLJ,

Ar(IKLJ) = length x breadth

= 2.5 x 80

= 200m²

Similarly find the area of rectangle EFGH,

Ar(EFGH) = length x breadth

= 40 x 2.5

= 100m²

Finally find the area of square MNOP,

Ar(MNOP) = side²

= 2.5²

= 6.25m²

So area of unshaded region will be,

Ar(unshaded) = Ar(ABCD) - Ar(IKLJ) - Ar(EFGH) + Ar(MNOP)

= 3200 - 200 - 100 + 6.25

= 2900 + 6.25

= 2906.25m²
