Question

Perimeter of a rectangle is 18 cm. Its sides are in the ratio 3 : 4. Draw the rectangle.

Answer 1

Step-by-step explanation:

Perimeter of rectangle = 18 cm Sides are in the ratio = 3 : 4 Step of construction :

(i) Draw XY = 9 cm.

(ii) Make ∠YXZ < 90° and mark the points A1, A2, A3, A4, A5, A6 and A7. Such that XA1 = A1 A2 = A2 A3 = A3 A4 = A4 A5 = A5 A6 = A6 A7

(iii) Join A7 Y (iv) Make ∠XA7Y = ∠XA3P ∴ XP : PY = 3 : 4 (v) ∠SPY = 90°

(vi) Taking centre P and radius equal to XP draw a arc which intersect PS at the point Q. PQRY is a rectangle.Read more on Sarthaks.com - https://www.sarthaks.com/209543/perimeter-of-a-rectangle-is-18-cm-its-sides-are-in-the-ratio-3-4-draw-the-rectangle
