Question

what is the area of this figure? 8 cm 5 cm 7 cm 1 cm 2 cm 7 cm square centimeters

Explanation:

Step1: Calculate area of large rectangle

The large rectangle has length 8 cm and height 7 cm. Area formula: $A = l \times h$.
$A_1 = 8 \times 7 = 56$ $cm^2$

Step2: Calculate area of missing part

The missing part is a rectangle with length 1 cm and height 2 cm. Area formula: $A = l \times h$.
$A_2 = 1 \times 2 = 2$ $cm^2$

Step3: Subtract missing area from large area

Total area $A = A_1 - A_2$.
$A = 56 - 2 = 54$ $cm^2$

Answer:

54
