Question

find the area of the figure. (sides meet at right angles.)

Explanation:

Step1: Divide the figure into rectangles

The figure can be divided into three rectangles.

Step2: Calculate area of first rectangle

The first rectangle has sides 4m and 5m. Area $A_1 = 4\times5=20$ m².

Step3: Calculate area of second rectangle

The second rectangle has sides $(5 + 5+4)=14$m and 5m. Area $A_2=14\times5 = 70$ m².

Step4: Calculate area of third rectangle

The third rectangle has sides 5m and 5m. Area $A_3 = 5\times5=25$ m².

Step5: Calculate total area

Total area $A=A_1 + A_2+A_3=20 + 70+25=115$ m².

Answer:

115
