Question

The area of two equal circles in the figure
is 308 cm². Find the area of the rectangle​

Answer 1

Answer:

In the given figure, we have a rectangle of length 50 cm and width 10 cm, and two similar trapeziums with parallel sides 30 cm and 10 cm.

Suppose x is the perpendicular distance between the parallel sides in both the trapeziums.

We have,

Total length of the figure=Length of the rectangle+2×Perpendicular distance between the parallel sides in both the trapezium

⇒70=50+2×x

⇒2×x=20

⇒x=  

2

20

​  

 

⇒x=10 cm

Now, area of the complete figure=(Area of the rectangle with sides 50 cm and 10 cm)+2×(Area of the trapezium with parallel sides 30 cm and 10 cm)

=(50×10)+2×[
