Question

A sign is being made from a rectangular board of wood that originally measures 36 inches by

Answer 1

Solution (a):

• Area of rectangle = LB
• => Area of rectangle = 18 x 36
• => Area of rectangle = 648 in²

Solution (b):

Since the two triangles are equal (as said in the question):

• => Area of triangles: 2(1/2 x 6 x 18)
• => Area of triangles: 6 x 18
• => Area of triangles: 108 in²

Solution (c):

Subtract the area of the triangles from the area of the rectangle.

• 648 - 108 = Area of trapezoid
• => 540 in² = Area of trapezoid
