An angelfish was 1 1/2 inches long when it was bought. Now it is 2 1/3 inches long.

____ [38]

Earlier, The length of the angelfish = $1 \frac{1}{2}$ inches

Now, the length of angelfish = $2 \frac{1}{3}$ inches

We have to determine the grown length of angelfish

= $2 \frac{1}{3}$ - $1 \frac{1}{2}$

= $\frac{7}{3}- \frac{3}{2}$

LCM of '2' and '3' is '6',

= $\frac{14-9}{6}$

= $\frac{5}{6}$ inch

Therefore, the angelfish has grown by $\frac{5}{6}$ inch.

We have to determine the increased length of angelfish in feet.

Since $1 inch = \frac{1}{12}$ foot

So, $\frac{5}{6} inch = \frac{5}{6} \times \frac{1}{12} = \frac{5}{72}$

= 0.069 foot.

AC⊥BC

BD=BC=x

(x+5)²+x²=7²
x²+10x+25+x²=49
2x²+10x- 24=0
x²+5x-12=0
x=1.8

BC= 1.8 cm

Area of ABC= 1/2*1.8*7= 6.3 cm²
