The area of a rhombus is 90 square units. If one diagonal is 10 units, find the length of the other diagonal

18 units

Step-by-step explanation:

Area of rhombus is given by 1/2(product of length of diagonals).

Given

Area of rhombus = 90 sq. units

length of one diagonal = 10 units

let the length of other diagonal be x units

Substituing the value given above in formula for area of rhombus we have

90 = 1/2(10*x)

=> 90*2 = 10x

=> 180 = 10x

=> x = 180/10 = 18

Thus, length of other diagonal is 18 units.

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

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
