Answer:
The width of rectangle w = 4 units
Step-by-step explanation:
We are given:
Width of rectangle = w
Length of rectangle = w+ 4
Area of rectangle = 32 units
We need to find width of the rectangle
The formula used is: 
Putting values and finding width of rectangle

We need to solve this quadratic equation to find width (w)
We will use factorisation and break the middle term.

Since width of rectangle can't be negative, so rejecting w=-8
Therefore, the width of rectangle w = 4 units
This to numbers are equal
Answer:
A = 120 cm²
Step-by-step explanation:
The 4 part of the ratio relates to the height of triangle A , then
16 ÷ 4 = 4 cm ← value of 1 part of the ratio, then
5 parts = 5 × 4 cm = 20 cm
The area (A) of triangle B is calculated as
A =
bh ( b is the base and h the height )
Here b = 12 and h = 20 , then
A =
× 12 × 20 = 6 × 20 = 120 cm²
Answer:
Equilateral and acute
Step-by-step explanation:
Notice that the angles of the triangle are all 60 degrees which is less than 90 degrees. Also notice the lines in the middle of the triangle lines, those signify that the lines are the same length. Thus making it acute and equilateral
