Answer:
108 cm^2
Step-by-step explanation:
rectangle + 2 triangle = total area
L x W + 2 * 1/2 base * height = total area
(5x12) + 2 * 1/2 * 12 * 4 = total area
60 + 48 = 108 cm^2
108 cm²
To do:
1. find area of rectangle 2. find area of triangles 3. add them together
area of a rectangle = bxh = 5x12 = 60
area of triangle = (bxh)/2 = (12x4)/2 = 24
60+24+24=108
a=7
-52 = -17 -5a
Add 17 to each side
-52+17 = -17-5a+17
-35 = -5a
Divide by -5
-35/-5 = -5a/-5
7=a
