Answer:
58 cm^2
Explanation:
there are three rectangles in the shape
the first one on the left has length = 7 cm and width = 3 cm.
so area = l × w
= 7×3
=21 cm^2
the one in the middle has length = 4 cm and width = (7- 3) => 4cm
so area = 4 × 4
= 16 cm^2
the last one to the right is identical to the first, so area = 21 cm^2
The combined area = 21 + 16 + 21
= 58 cm^2
Answer:
b = 2
Step-by-step explanation:
Original Equation:
-12 + 3b - 1 = -5 - b
Add b to both sides
-12 + 4b - 1 = -5
Add 12 to both sides
4b - 1 = 7
Add 1 to both sides
4b = 8
Divide both sides by 4
b = 2
Hope this is what you need :)
