Answer:
Area =910 Perimeter = 14 units
Step-by-step explanation:
Area is the inside measurement: A = L× W
The area of the whole rectangle - the white section = the area of the blue section
Whole - the white
rect. rect.
A = (L x W) - (L x W)
A = ( 20 × 50) - (6 × 15) = 1000 - 90 = 910 sq. units
Remember that perimeter is the distance around the figure: P = 2L + 2 W
Perimeter = perimeter of the whole rect. - the perimeter of the white section.
Perimeter = 2(L) + 2(W) - 2(L) + 2 (W)
2(50) + 2(20) - (2(6) + 2(15))
(100 + 40) - (12 + 30)
140 - 36
104
