Question

find the area.
a. 1818 sq cm
b. 1406 sq cm
c. 1246 sq cm
d. 141 sq cm
e. 146 sq cm

Explanation:

Step1: Split shape into two rectangles

We can divide the figure into a larger lower rectangle and a smaller upper rectangle.
For the lower rectangle: length = $39$ cm, height = $26$ cm.
For the upper rectangle: length = $29$ cm, height = $34 - 26 = 8$ cm.

Step2: Calculate area of lower rectangle

Area = length $\times$ height
$\text{Area}_1 = 39 \times 26 = 1014$ sq cm

Step3: Calculate area of upper rectangle

Area = length $\times$ height
$\text{Area}_2 = 29 \times 8 = 232$ sq cm

Step4: Sum the two areas

Total area = $\text{Area}_1 + \text{Area}_2$
$\text{Total Area} = 1014 + 232 = 1246$ sq cm

Answer:

C. 1246 sq cm
