Answer:
216 cm^2.
Step-by-step explanation:
Surface area = 2 * area of triangular sides + area of 3 rectangles
= 2 * 1/2 * 6 * 8 + 8*7 + 6 * 7 + 10*7
= 48 + 56 + 42 + 70
= 216.
Answer:
216cm^2
Step-by-step explanation:
The surface area is equal to the sum of areas of the walls.
We've got 2 triangular walls with area 6*8/2, for 6*8 = 48cm^2 total
We've got a wall with 7x10 = 70cm^2
We've got a wall with 6x7 = 42cm^2
And the last wall is 8x7 = 56cm^2
So total surface area is: 48 + 70 + 42 + 56 = 216

Answer:
length = 8; width = 3
perimeter = 22
area = 24
Step-by-step explanation:
L(- 1,3), M(2,3)
LM = |-1 - 2| = 3
M(2,3), N(2, - 5)
MN = |-5 - 3| = 8
length = 8; width = 3
perimeter = 2(L + W) = 2(8 + 3) = 22
area = LW = 8 × 3 = 24
