Question

Write 'T' for true and 'F' for false

(i) Area of a triangle = (base × height)
(ii) Area of a || gm = (base × height)
(iii) Area of a circle = $2{\mathrm{\pi r}}^2$
(iv) Circumference of a circle = $2\mathrm{\pi r}$

Answer 1

(i) F
Area of a triangle = $\frac{1}{2}\times \mathrm{Base}\times \mathrm{Height}$

(ii) T
Area of a parallelogram = Base × Height

(iii) F
Area of a circle = ${\mathrm{\pi r}}^2$

(iv) T
Circumference of a circle = $2\mathrm{\pi r}$2πr2
