A rectangle has an area of 45 square inches. The height of the rectangle is 9 inches. What is the width of the rectangle?

what the hеll boi

Step-by-step explanation:

this is basic math lmао

5in

Step-by-step explanation:

The formula for area is A=bh or Area = Base × Height

or you can write it as A=wh which is Width × Height

so plug in the numbers you already know

(do not worry about units right now)

45=b(9)

Now you have to get the variable b by itself

divide both sides by 9 to get b by itself

45(÷9)=b(9)(÷9)

the 9 next to the b gets canceled out

45÷9= 5

The answer is 5 inches

Always remember that the actual area's units are squared while the base and height are just the unit not squared

45in²=area

5in and 9in= base and height

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
