Question

find the area of the composite shape. area 1 = 28 cm² area 2 = ____ cm²

Explanation:

Step1: Identify the shape of Area 2

Area 2 is a rectangle with length 9 cm and height 11 cm.

Step2: Use the formula for the area of a rectangle

The formula for the area of a rectangle is \( A = l \times h \), where \( l \) is the length and \( h \) is the height.
Substituting \( l = 9 \) cm and \( h = 11 \) cm into the formula, we get \( A = 9 \times 11 \).

Step3: Calculate the product

\( 9 \times 11 = 99 \).

Answer:

99
