Answer:
2212.5 cm²
Step-by-step explanation:
ABCD is constructed from 2 right triangles ABD and BCD
The area (A ) of a triangle is calculated using the formula
A = bh ( b is the base and h the perpendicular height )
In ΔABD, b = AD = 60 and h = AB = 25, hence
A = × 60 × 25 = 30 × 25 = 750 cm²
-----------------------------------------------------------------------------
In ΔBCD, b = BD = 65 and h = CE = 45, hence
A = × 65 × 45 = 1462.5 cm²
----------------------------------------------------------------------------
The area of figure ABCD = area of ΔABD + area of ΔBCD
A = 750 + 1462.5 = 2212.5 cm²
Answer:
<h2>x < - 2</h2>Step-by-step explanation:
First subtract 7x from both sides of the inequality
That's
<u>Add 10 to both sides of the inequality</u>
<u>Divide both sides by - 15</u>
Since the denominator is negative the sign will change
We have the final answer as
<h3>x < - 2</h3>Hope this helps you
Answer:
Step-by-step explanation:
Given
Shape: Rectangle
Required
Determine the dimensions
The perimeter of a rectangle is:
Substitute 120 for Perimeter
Divide both sides by 2
Substitute 3 * Height for Base
Divide both sides by 4
Substitute 15 for Height in
