The area of a rectangle is 63 inches squared and the base is 15 inches. Find the height of the rectangle

4.2 inches

Step-by-step explanation:

Area of rectangle = base × height

base b, = 15 inches

height h, = unknown

area = 63 inches²

63 = 15 × h

h = 63/15

= 4.2 inches

Area of rectangle = 63

base × height = 63

height × 15 = 63

base = 63/15 = 4.2 in

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
