Question

NO LINKS!! Similar figures are given. Use the given area to find the measure of XY.​

Answer 1

Answer:

$\textsf {See below :-}$

Step-by-step explanation:

$\textsf {Relation to keep in mind :}$

$\implies \mathsf {Area = length^{2}}$

$\textsf {Question 34}$

$\implies \mathsf {\frac{135}{15} = (\frac{15}{XY})^{2} }$

$\implies \mathsf {XY^{2} = \frac{15^{3}}{135}}}$

$\implies \mathsf {XY = 5}$

$\textsf {Question 35}$

$\implies \mathsf {\frac{378}{168} = (\frac{XY}{8})^{2} }$

$\implies \mathsf {XY= \sqrt{\frac{378 \times 64}{168}}}$

$\implies \mathsf {XY = \sqrt{144}}$

$\implies \mathsf {XY = 12}$

Answer 2

Remember for any two polygons

Area of polygons is directly proportional to square of sides

So

• BC²/XY²=135/15
• 15²/XY²=9
• (15/3)²=XY²
• XY=5in

#35

• HJ²/XY²=168/378
• 8²/XY²=0.44
• XY²=64/0.44
• XY²=145.45
• XY\approx 12+
