Answer:
(a)=4 1/2inch
(b)=27/32 inch
Step-by-step explanation:
(a) Area of a rectangle =
A = width × length
50 5/8 = (11 1/4×L)
convert from mixed to proper or improper fraction
405/8=45L/4
cross multiply
405×4=45L×8
1620 = 360L
divide by 360
1620/360 = 360L/360
9/2 inches
CONVERT THE ANSWER BACK TO MIXED FRACTION
4 1/2inches
(b) We are asked to find the perimeter
p = 2(w + L)
p = 2(3/4 × 9/16)
Multiply the numerators together and the denumerator together
p = 2(3×9/4×16)
p = 2(27/64)
open the bracket
p = 27/32 inch
