Answer:
8.2 m
Step-by-step explanation:
Divide 37.72 (area) by 4.6 (height) to find the base. H x b = A
Answer:
DC= 32.3 units
Step-by-step explanation:
Use Pythag theorem to find BC first
15 ^2 + BC ^2 = 22^2 then BC = sqrt 259
Then use the Pythagorean Theorem again to find DC
DC^2 = 28^2 + sqrt(259)^2
DC=32.3
Area:
The expression for area would be length x width, therefore the expression would be (3x + 1)(2x -7)
Perimeter:
There are many expressions for perimeter. Here are some of them:
Length + width + length + width
2length + 2width
2(length + width)
Let's use the first one, for example. The expression would be (3x + 1) + (2x - 7) + (3x + 1) + (2x -7).
