Question

What the answer of this question?

Answer 1

2.5

Explanation:

equation the two areas in an equation and they are equal

`(1)/(2) base * height = length * \: width`

but the width is w

substituting the values,

`(1)/(2) (6)(5) = 6 * w \\ 15 = 6w \\ w = (15)/(6 =) = (5)/(2 ) = 2.5`

Answer 2

w = 3 cm

Explanation:

The area (A) of the triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the height )

Here b = 5 and h = 6 , then

A =
`(1)/(2)` × 5 × 6 =
`(1)/(2)` × 30 = 15 cm²

Now the area of the rectangle is 15 cm²

area = length × width , that is

5w = 15 ( divide both sides by 5 )

w = 3 cm
