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

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
