Exercise 62 Page 838

The area of a rhombus is half the product of its diagonals.

253ft^2

Practice makes perfect

We are given a rhombus and asked to find its area.

The area of a rhombus is half the product of its diagonals. A = 1/2d_1d_2 We can see from the diagram that the lengths of the diagonals are d_1 = 22ft and d_2 = 23ft. We can find the area of the rhombus by substituting those values into the formula. Let's do it!

A = 1/2d_1d_2

d_1= 22, d_2= 23

A = 1/2( 22)( 23)

Multiply

A = 253

The area of the rhombus is 253ft^2.
