Area of a triangle = 1/2 × base × height
Plug in what we know.
78 = 1/2 × b × 9¾
Multilply each side by 2 to get rid of the 1/2...
156 = b × 9¾
Write 9¾ as an improper fraction.
(9¾ = 9 + 3/4 = (9×4)/4 + 3/4 = 36/4 + 3/4 = 39/4)
156 = b × 39/4
Multiply each side by 4...
624 = b × 39
Divide each side by 39...
16 = b
Done! The length of the base of the triangle is <u>16</u> inches.
Answer:
w is greater than or equal to 358
Answer:
yes
Step-by-step explanation:
side 1
(2,8) to (2,2)
8-2 = 6 (length of this side)
side 2
(2,2) to (-4,2)
2-(-4) = 6
side 3
(-4,2) to (-4,8)
8-2 = 6
side 4
(-4,8) to (2,8)
2- (-4) = 6
* note: it doesn't matter the order of subtraction because length can't be negative (so just make sure your answer is positive) , also don't subtract the side that is constant, you will get 0, a side can not be 0 cm
to find the area of a square multiply length by width
6 x 6 = 36
