Answer:
Step-by-step explanation:
<u>We know that:</u>
- Length = (4m + 7)
- Breadth = (3m + 2)
The perimeter of a shape is the sum of its boundaries. Let's represent perimeter as p.
<u>Solution:</u>
- p = (4m + 7) + (4m + 7) + (3m + 2) + (3m + 2)
- => p = 2(4m + 7) + 2(3m + 2)
Hence, the algebraic expression on how to find the perimeter is 2(4m + 7) + 2(3m + 2).
3•7=21 if times three times seven it equals twenty one
Answer:
70 centimeters squared
Step-by-step explanation:
area of trapezoid formula is 1/2 (b1 + b2)
1/2 (7+13)(7)
7 is base 1, 13 is base 2, 7 is the height
1/2(7+13)(7)
1/2(20)(7)
1/2(140)
70
