A standard interior staircase has steps each with a rise (height) of 21 cm and a run (horizontal depth) of 24 cm. Research sugge
Alisiya [41]

Answer:

The staircase would extends 1.20 m if the changes were made.

Step-by-step explanation:

Acording tho the statement the total heigth is 5.04 m, that is 504 cm, each steps rises 21 cm. with this information we can calculte how many steps are in the whole staircase:

Number steps= \frac{Total heigth}{each step} \\Number steps= \frac{504}{21}  = 24 steps

To calculate how much the staircase will extend, whe have to multiply the horizontal depth times the number of steps.

using the run of 24 cm that gives us a lengt of 576 cm and if the changes were made the new length will be 696 cm.

So the staircase would extend an amount of (696 - 576), that is 120 cm, or 1.20 m, if the changes were made.

A rectangular field has the area equal to that of a square field of side 60m.if the breadth of the rectangular field is 32m, fin
V125BC [204]

<u>Given</u> -

  • Area of rectangular field = Area of square field
  • side of square = 60m
  • breadth of the rectangular field = 32m

<u>To find</u> -

  • length of the rectangular field

<u>Solution</u> -

Area of square = side × side = (60 × 60)m² =

Area of square =3600m²

Hence,

Area of rectangular field = Area of square field = 3600m²

Area of rectangular field = l × b = 3600m²

=> l × 32m = 3600m²

=> l = \sf{\frac{3600}{32}\:m}

=> l = 112.5m

so, the length = 112.5m
