Question:
Perimeter of quadrilateral is 47 cm, find AD.
To find:
★ The value of AD
Answer:
[tex] \bf{\underline{ \: \underline{ \: AD \: is \: 10 \: cm} \: }\: }[/tex]
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
[tex] \hookrightarrow AB+BC+CD+AD = 47[/tex]
[tex] \hookrightarrow 10 + 15 + 12+AD = 47[/tex]
[tex] \hookrightarrow 37+AD = 47[/tex]
[tex] \hookrightarrow AD = 47 - 37[/tex]
[tex] \hookrightarrow \boxed{ \bf{AD = 10 \: cm}}[/tex]
[tex] \therefore \bf{ \underline{AD \: is \: 10 \: cm}}[/tex]
