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

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and
