Answer 2

Question:

Perimeter of quadrilateral is 47 cm, find AD.

To find:

★ The value of AD

Answer:

$\bf{\underline{ \: \underline{ \: AD \: is \: 10 \: cm} \: }\: }$

Given:

Perimeter of quadrilateral = 47 cm

Step-by-step explanation:

Perimeter of quadrilateral = 47 cm

We know that,

Perimeter means Sum of all sides .

Sum of all sides = AB + BC + CD + AD

$\hookrightarrow AB+BC+CD+AD = 47$

$\hookrightarrow 10 + 15 + 12+AD = 47$

$\hookrightarrow 37+AD = 47$

$\hookrightarrow AD = 47 - 37$

$\hookrightarrow \boxed{ \bf{AD = 10 \: cm}}$

$\therefore \bf{ \underline{AD \: is \: 10 \: cm}}$

More information:

A quadrilateral has:

★ Four sides (edges).

★ Four vertices (corners).

★ Interior angles that add to 360 degrees.

★ A quadrilateral is a two-dimensional shape.
