a) area of a triangle = (base X height) / 2 = 16X9/2 = 72cm squared
b) area of a parallelogram = (base X height) = 26 X 14 = 364 in squared
c) area of a square = (base X width) = 11 X 11 - 121 yds sqaured
d) are of a trapezoid (the hardest) =
(top bases + bottom base) /2 all times height
(6 + 21) /2 times 8
126/2 times 8
63 times 8 = 504 ' squared
If 3/5 of a number is 18, that means that 1/5 is 6 as 18/3 = 6. Since 1/5 is equal to 2/10. 1/10 of the number = 3. 7/10 of the number is 3*7 which is 21.
