Answer:
Step-by-step explanation:
The diagonal ^2= 13^2+7^2
=169+49=218
diagonal = V218
the lengh of the square=l
l^2+l^2= 218
2l^2=218
l^2= 218/2= 109
l= ✓109
Answer:
A
Step-by-step explanation:
Area of a square=L^2
Area=(7a4b8)^2
Area=49a8b16
Answer:
D
Step-by-step explanation:
Given
- (x + 3) - 2(4x - 3) ← distribute both parenthesis
step 1
= - x - 3 - 8x + 6 ← collect like terms
step 2
= - 9x + 3
The hexagon is made up of 6 triangles. So we need to multiply the area of the triangle by 6 to find the answer.
Area of triangle = b x h / 2
A = 14 x 12.1 / 2
A = 169.4 /2
A = 84.7 ft squared
Area of hexagon = 84.7 x 6
= 508.2 ft squared
