Answer 1

Answer:

(i) 80 unit²

(ii) 500 unit²

(iii) 1050 unit²

(iv) 750 unit²

Step-by-step explanation:

Using formulas of area of triangle and rectangle, we get

(i) Required Area = area of shaded triangle

A = 1/2 * (30-22) * 20 = 80 unit²

(ii) Required Area = area of rectangle - area of unshaded triangle

A = (40*25) - (1/2 * 40*25) = 500 unit²

(iii) Required Area = area of rectangle - area of unshaded triangle

A = (30*50) - (1/2 * (30-12)*50) = 1500-450 = 1050 unit²

(iv) Required Area = area of rectangle - area of unshaded triangle

A = (60*35) - {(1/2 * 40*35) + (1/2 * 20 *20) + (1/2 * 60 *15)} =

=> A = 2100-{ 700 + 200 +450 }

=> A = 2100 -1350 = 750 unit²
