Question

the area of shaded region​

Answer 1

Answer:

area of shaded region= area of rectangle 1 + area of rectangle 2 - area of square at the center

area of rectangle 1 = L ×B

• L= 40m
• B=1m

area = 40×1= 40m^2

area of rectangle 2 =L×B

• L=1m
• B=50m

area=1×50=50m^2

area of square = side × side

• side=1m

area=1×1=1m^2

area of shaded region=40+50-1=89m^2

Answer 2

Answer:

89m^2

Step-by-step explanation:

given:length=50mand breath=40m

Area of the 1m shaded strip along length=50m×1m=50m^2

Then,the breath=40m-1m shaded strip =39m

Area of the 1m shaded strip along breath=39m×1m=39m^2

Area of the whole shaded portion =50m^2+39m^2

=89m^2
