Question

The perimeter of the rectangle whose length is 24cm and a diagonal 26cm is​

Answer 1

Step-by-step explanation:

Length of rectangle (l) is 24 cm.

Length of diagonal (d) is 30 cm.

Let the length of breadth be b.

Write the formula to calculate the diagonal of rectangle.

d=

b

Substitute the values in equation (1).

30

b

+(24)

Solve for b.

=324

b=±18

Since, the breath cannot be negative. So, neglect the negative value of breadth. Hence, the breadth of the rectangle is 18 cm.

Write the formula to calculate perimeter of rectangle.

P=2(l+b) (2)

Substitute the values in equation (2).

P=2(24+18)

=2(42)

=84

Thus, the perimeter of rectangle is 84 cm.
