Question

find the area of a parallelogram whose base is 14 cm and height is 5 cm​

Answer 1

Answer:

70 cm2

Step-by-step explanation:

Area = base × height

Area = 14 × 5

Area = 70 cm2

Answer 2

$\underline{\frak{Diagram:}}$

$\setlength{\unitlength}{1 cm}\begin{picture}(0,0)\thicklines\qbezier(1,1)(1,1)(6,1)\put(0.4,0.5){\bf D}\qbezier(1,1)(1,1)(1.6,4)\put(6.2,0.5){\bf C}\qbezier(1.6,4)(1.6,4)(6.6,4)\put(1,4){\bf A}\qbezier(6,1)(6,1)(6.6,4)\put(6.9,3.8){\bf B}\end{picture}$

$\underline{\frak{Given:}}$

$\qquad\quad\bullet\:\textsf{Base of parallelogram = 14 cm}$

$\qquad\quad\bullet\:\textsf{Height of parallelogram = 5 cm}$

$\underline{\frak{To\:Find:}}$

$\qquad\quad\bullet\:\textsf{Area of parallelogram = ?}$

$\underline{\frak{Solution:}}$

☯ $\underline{\boldsymbol{According\: to \:the\: Question\:now :}}$

$:\implies\sf Area_{(of \: parallelogram)} = Base \times Height$

$:\implies\sf Area_{(of \: parallelogram)} = 14 \times 5$

$:\implies \underline{ \boxed{\sf Area_{(of \: parallelogram)} = 70 \: {cm}^{2}}}$
