Answer:
Step-by-step explanation:
A kite consists of two pairs of congruent adjacent sides. Therefore, we have the following equation:
, where
is the length of the shorter sides.
Solving, we get:
.
Plugging in into
, we get:
.
Therefore, two sides have length and two sides have length
.
The area of a 2D form is the amount of space within its perimeter. The correct option is D.
<h3>What is an area?</h3>The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of the L block will be the sum of the area of A and B. Therefore, the area can be written as,
Area of L block = Area of A + Area of B
= (7×2) units² + (1 × 5) units²
= 14units² + 5units²
= 19units²
Hence, the correct option is D.
