Answer:
Step-by-step explanation:
(a) first we find the unshaded area than we will subtract it from whole area
area of rectangle =l x w =15 x 5 =75
Area of a square =s x s = 10 x 10 =100
total area of a rectangle= 42 x 40=1680
1680-175=1505 answer
(b) Are equals to side x side so:
4 x 1 =4
4.5x 1 =4.5
3 x 4=12
we will add all the area : 12+4+4.5 =20.5 answer
(c) 9 x 2 =18
2 x 7= 14
add both areas 18+14= 32
