One diagonal of a kite is twice as long as the other diagonal. If the area of the kite is 400 square meters, what are the length

san4es73 [151]

Answer:

20m and 40m

Step-by-step explanation:

The area (A) of a kite is calculated using the formula

A = $\frac{1}{2}$ product of diagonals

Let one diagonal be d then the other diagonal is 2d ( twice as long )

Hence

$\frac{1}{2}$ × 2d × d = 400

d² = 400 ← take the square root of both sides

d = $\sqrt{400}$ = 20

and 2d = 2 × 20 = 40

The diagonals are 20m and 40m in length

2. JI. has coordinates J(-6, 1) and Z(-4, 3). Find the coordinates of the midpoint.

AleksandrR [38]

Answer:

(- 5, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ )

Here (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 4, 3) thus

midpoint = $\frac{-6-4}{2}$ , $\frac{1+3}{2}$ ) = ( $\frac{-10}{2}$ , $\frac{4}{2}$ ) = (- 5, 2 )
