I got my perimeter and area of rectangle is also correct, but having trouble with area of the triangle. Area of a triangle is A = (1/2)bh or in this problem A=(1/2)(8)(15). You do not use the 17 which is the side of the triangle. ?

the perimeter is 76ft

the side of the triangle is the same as the side of the rectangle (15)

so 15×8=120 120/2=60

so the area of the triangle is 60 so add that to the area of the rectangle and get

the area is 330ft squared

d i think

step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
