Question

find the rectangle whose side are prime number and each has a perimeter of 40cm. calculate the area of the two rectangle​

Answer 1

Answer:

There can be only 2 rectangles which can be formed so that their perimeter adds up to 40 m.

The combination of sides is:

• 3 m, 17 m
• 7 m, 13 m

Area of the rectangles:

When combination is 3m and 17 m:

Area = lb = 3 × 17

Area = 51 sq. m

When combination is 7 m and 13 m:

Area = lb = 7 × 13

Area = 51 sq. m

Thus, the area of two rectangles is the same if their perimeter is same.
