Answer:
836 cm^2
Step-by-step explanation:
30 *30 = 900
4*4=16 *4=64
900-64 = 836cm^2
Answer:
k=4
Step-by-step explanation:
First, distribute the 2 on the left side
2 (k - 5) + 3k = k + 6
2*k +2*-5 +3k=k+6
2k-10+3k=k+6
Combine like terms on the left side
5k-10=k+6
Add 10 on both sides
5k=k+16
Subtract k on both sides
4k=16
Divide by 4 on both sides
k=4
Hope this helps! :)
BCDE is a square of 576 square feet, so each side is √576=24 feet
BE=24
BF:FE=2:1, so BF=16, FE=8
Area of ABF is half of BE times AE (AE is the height): 1/2 of 16*12=96
the answer is 96 square feet
