Question

A rectangular punch has A hieght of 18mm and its area is 630mm2. Calculate the length.

Answer 1

Area of rectangle = l*b
630mm²=l*18mm
630/18=l
35=l
therefore L = 35 mm

Answer 2

Answer:

35cm is the required length  of the rectangular punch .

Step-by-step explanation:

Explanation:

Given , height of rectangular punch = 18mm

and  area of rectangular punch = 630$mm^2$

Let the length be x mm .

Area of rectangle = length × width

Step 1:

From the question we have ,

h = 18mm and area =  630$mm^2$

Area of rectangular punch = x × 18

⇒630 = 18x

⇒x = $\frac{630}{18 }$ = 35 mm.

Final answer :

Hence , the length of the rectangular punch 35mm.
