Asap. solve both. will mark brainliest. show work.

1. Area= Length × Width
50 5/8= L × 11 1/4
50 5/8 ÷ 11 1/4= L

L= 4.5 inches

(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
