Arectangle measures 1 1/ 2 inches by 3/ 4 inches. what is its area? i will mark brainliest and 100 points

[|] Answer [|]

[|] Explanation [|]

Convert 1 1/2 and 3/4 into mixed numbers:

1 1/2 = 3 /2

3 / 4 = 3 / 4

Multiply Across:

3 * 3 = 9

2 * 4 = 8

= 9 / 8

Simplify:

1 1/8

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
