Area of a triangle = 1/2 (b*h)
100 = 1/2 (b * 10)
200 = b * 10
b = 200/10
b = 20 cm
Hope this helps.

If the area of a triangle is A=bh%2F2
given:
A=+100cm%5E2
h=10cm
find the length of the base b
A=bh%2F2...plug in given values
100cm%5E2=%28b%2A10cm%29%2F2
2%2A100cm%5E2=b%2A10cm
200cm%5E2%2F10cm=b
20cm=b
