Area of a rectangle = Length * Width
Area = 60cm^2
Length = 4
Width = GH = ? = x
60 = 4*x
solve for x
60/4 = x
x = 15
GH is 15cm
There are 63 students in the room, this is because 21 time 3 gives you 63.
Answer: ok so for 5 and 125 it is 65 and 25
for 1 and 9 it is 5 and 3 and for 4 and 9 it is 13/2 and 6
892 x 18 = 16,056
First multiply 2 with 18 and do the same with 9 and 8 then multiply 2 with one and do the same with 9 and 8 then add up the two sums which give you 16,056
Because this shape has 2 right angles, we can confirm that it has one set of parallel sides and is a trapezoid. Therefore, use the formula for area of a trapezoid, .5(b1+b2)(h)
.5(1+6)(12)
.5(7)(12)
42 units^2
