Question

6. The base of a triangle is twice its height. If the area of the triangle is 25 cm², then the base is
(a) 10 cm
(b) 20 cm
(c) 5 cm
(d) 25 cm.​

Answer 1

Step-by-step explanation:

Let the height of the triangle be h

then base is 2h

area of triangle=½×2h×h

25=½×2h×h

h²=25

h=5

therefore base is 2h=2×5=10cm
