Question

draw an equiletral triangle one of whose sides is of length 5 cm​

Answer 1

Step-by-step explanation:

Draw PQ=AB+2h=3. 3 cm.

At the point Q and P, draw angles of 90˚ on the same side of PQ.

Cut those perpendicular lines at 3. 3 cm at R and S.

Join RS.

Area of square PQ×QR=3. 3×3. 3 cm2≈10. 89 cm2.
